Relugolix combination tablet (relugolix 40 mg, estradiol 1.0 mg, and norethindrone acetate 0.5 mg) is under regulatory review in?Europe?and the?U.S.?for women with uterine fibroids and is under development for women with endometriosis. About ORGOVYX??(relugolix) ORGOVYX (relugolix) is the first and only oral gonadotropin-releasing hormone (GnRH) receptor antagonist approved by the FDA for the treatment of adult patients with advanced prostate cancer. As a GnRH antagonist, ORGOVYX blocks the GnRH receptor and reduces production of testicular testosterone, a hormone known to stimulate the growth of prostate cancer.

Select Important Safety Information Androgen deprivation therapy, such as ORGOVYX, may?prolong the QT/QTc interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, or frequent electrolyte abnormalities and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes. The safety and efficacy of ORGOVYX have not been established in females. Based on findings in animals and mechanism of action, ORGOVYX can cause?fetal harm and loss of pregnancy?when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 2 weeks after the last dose of ORGOVYX. Most common adverse reactions (= 10%)?in patients receiving ORGOVYX were hot flush (54%), musculoskeletal pain (30%), fatigue (26%), constipation (12%), and diarrhea (12%). Most common laboratory abnormalities (= 15%)?in patients receiving ORGOVYX were glucose increased (44%), triglycerides increased (35%), hemoglobin decreased (28%), alanine aminotransferase increased (27%), and aspartate aminotransferase increased (18%). Co-administration of ORGOVYX with a P-gp inhibitor?increases the area under the curve (AUC) and maximum concentration (C_max) of ORGOVYX, which may increase the risk of adverse reactions associated with ORGOVYX. Avoid co-administration of ORGOVYX with oral P-gp inhibitors. If co-administration is unavoidable, take ORGOVYX first, separate dosing by at least 6 hours, and monitor patients more frequently for adverse reactions. Co-administration of ORGOVYX with a?combined P-gp and strong CYP3A inducer?decreases the AUC and C_max?of ORGOVYX, which may reduce the effects of ORGOVYX. Avoid co-administration of ORGOVYX with combined P-gp and strong CYP3A inducers. If co-administration is unavoidable, increase the ORGOVYX dose to 240 mg once daily. About?Myovant Sciences?
